XFEM4U Selection
Make selections
For selecting a (big) amount of nodes or beams in one time you can use the Select window or Select crossing.
This works exactly the same way as you might know from a.o. AutoCAD.
You draw a window from left to right. You draw a crossing from right to left.
Select window ( from left bottom to the right top)
1) Determine, using your mouse, the starting point of the window that you want to draw. This is the left corner of the window you want to draw.
2) Push the left mouse button
3) While you push the left mouse button you move the mouse to the right. A window is drawn in (partly transparent) blue.
4) When you release the left mouse button, all the nodes and beams that are completely in this window will be selected.
Select crossing ( from the right top to the left bottom)
1) Determine, using your mouse, the starting point of the window that you want to draw. This is the right corner of the window you want to draw.
2) Push the left mouse button.
3) While you push the left mouse button you move the mouse to the left. A window is drawn in (partly transparent) green.
4) When you release the left mouse button, all the nodes and beams that are partially in this window will be selected.
Multi select
To select multiple nodes or beams you can use the CRTL-button.
By pushing the CRTL-button continuously, you 'draw' the selection window as is described above.
Unselect
To unselect multiple nodes or beams you can use the SHIFT-button.
By pushing the SHIFT button continuously, you 'draw' the selection window as is described above.
Look at this demo in which a few possibilities of select window/ crossing are shown.
